Abstract:
A liquid ejecting head includes a first individual flow path and a second individual flow path that are adjacent to each other, a first common liquid chamber and a second common liquid chamber. In the first individual flow path, a first communication flow path extending between the first common liquid chamber and a first nozzle, and an inertance of the first communication flow path is smaller than an inertance of a second communication flow path extending between the second common liquid chamber and the first nozzle. In the second individual flow path, a third communication flow path extending between the second common liquid chamber and a second nozzle, and an inertance of the third communication flow path is smaller than an inertance of a fourth communication flow path extending between the first common liquid chamber and the second nozzle.
